dTomato with RBS
Figure 1. dTomato expressed with an inducible promoter.
The dTomato protein is a fluorescent dimer protein that emits orange-red light when it is excited by green-yellow light. It is preferable to use – especially in self-made fluorometry tests – because the excitation wavelengths and the emission wavelengths don't overlap as much as in other fluorescent proteins. The dTomato excitation peak is at 554 nm and 50% of it is at 510 nm. Also, its emission peak is at 581 nm and its 50% emission at 629 nm (Figure 1). Characterization has been made with the Anderson promoters BBa_J23101 (construct BBa_K1688010) and BBa_J23110 (construct BBa_K1688011)
